Definition
A nine-digit tax identification number issued by the U.S. Internal Revenue Service (IRS) to businesses, including sole proprietorships, LLCs, and corporations. For creators operating as a business entity in the United States, an EIN is required to open a business bank account, file business taxes, hire employees or contractors, and receive payments from brands and platforms without using a personal Social Security Number. Obtaining an EIN is a critical step in professionalizing a creator business and separating personal and business finances.
